Turkey wedding bomb: Suicide bomber who killed at least 51

Speaking live on national television in front of Istanbul's city hall, Recep Tayyip Erdogan said the attacker was aged between 12 and 14 and had wounded 69 people, 17 of which were in a critical condition.

"It was clear that Daesh had such an organization in Gaziantep or was attempting to make room for itself in recent times," President Erdogan said, using an alternative acronym for Isis.

"Many intensive operations were conducted, are being conducted. Of course our security forces will be conducting these operations with even greater intensity."
